COALESCER / SEPARATOR VESSELSKaydon Filtration 121A and 851E series are diesel fuel/water separation and filtration vessels that employ coalescing technology to separate water from diesel fuel. This fuel-purifying technology protects today’s highly sophisticated fuel injection systems, thereby keeping diesel-powered equipment in service. In addition to water removal, the coalescer provides a particulate filtration layer to remove harmful particulates, along with providing protection for the coalescing stage. Kaydon’s coalescing technology enables clean fuel delivery and prevents premature replacement of expensive components and revenue loss from equipment downtime resulting from contaminated fuel.

Model 851E Series Diesel Fuel / Water Separators

The Model 851E series of fuel/water separator vessels are industrial diesel fuel #1 and #2 filter vessels that utilize Kaydon Filtration coalescing technology and particulate removal capabilities. They remove damaging water and capture destructive particulates. The 851E series has a particulate performance rating of ISO Cleanliness Code < 18/16/131 and water removal to less than 130 ppm2.

The 851E series protects the fuel injection system and removes the burden of contamination control from the on-engine filters. They offer clean fuel delivery, preventing premature replacement of components and revenue loss from equipment downtime resulting from contaminated fuel.

The 851E series of fuel/water separator vessels can be configured with a wide array of options such as an automatic water drain, automatic air release, differential pressure gauge and pressure relief valve. Contact Kaydon technical support for more information on these available options.
